Nate Lawson c0b9a6de4a Disable interrupts while testing the timer. Not doing this unnecessarily ... added an arbitrary delay to our readings, causing us to use the ACPI-safe read method when not necessary. Submitted by: bde Old: ACPI timer looks GOOD min = 3, max = 5, width = 2 ACPI timer looks BAD min = 3, max = 19, width = 16 ACPI timer looks GOOD min = 3, max = 5, width = 2 ACPI timer looks GOOD min = 3, max = 5, width = 2 ACPI timer looks GOOD min = 3, max = 5, width = 2 ACPI timer looks GOOD min = 3, max = 4, width = 1 ACPI timer looks GOOD min = 3, max = 5, width = 2 ACPI timer looks BAD min = 3, max = 19, width = 16 ACPI timer looks GOOD min = 3, max = 5, width = 2 ACPI timer looks GOOD min = 3, max = 4, width = 1 Timecounter "ACPI-safe" frequency 3579545 Hz quality 1000 New: ACPI timer looks GOOD min = 3, max = 4, width = 1 ACPI timer looks GOOD min = 3, max = 4, width = 1 ACPI timer looks GOOD min = 3, max = 4, width = 1 ACPI timer looks GOOD min = 3, max = 4, width = 1 ACPI timer looks GOOD min = 3, max = 4, width = 1 ACPI timer looks GOOD min = 3, max = 4, width = 1 ACPI timer looks GOOD min = 3, max = 4, width = 1 ACPI timer looks GOOD min = 3, max = 4, width = 1 ACPI timer looks GOOD min = 3, max = 4, width = 1 ACPI timer looks GOOD min = 3, max = 4, width = 1 Timecounter "ACPI-fast" frequency 3579545 Hz quality 1000 Also, reduce unnecesary overhead in ACPI-fast by remove the barrier for reads. The timer in the ACPI-fast case is known to increase monotonically so there is no need to serialize access to it.		2004-04-24 16:25:00 +00:00
